Improvement in book-binding



I. BL-CKMAN, OF COLUMBUS,` MISSISSIPPI.

Leners Patent No. 89,622, dated May 4, 1869.

IMPROVEIWEN T IN' .BOOli-BILI'DIILWG'.

w l The Schedule referred to in thse Letters'Patent and making pan-.fof the same.

VTo all whom it may concern Be it known that I, W. I. BLACKMAN, of Columbus,

Lowndes county, Mississippi, have invented a' new and useful Improvement in Book-Binding; and Ido hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to makeand use the same, reference being had parts.

A represents a book, (without a cover,) lwith the leaves secured together, according to my invention.

Instead ofpiercing the leaves, and passing through the twine, (as is usually done in book-binding,) I make Atwo slits (as seen at B B, -in tig. 1,) across the back, and also as seen, in g. 2, at() C, leaving( a dovetail piece, D, between the slits.

The fastening-twine is drawn down into these slits, where it is tightly glued and tied, after passing under it the tapes E, for fastening on Vthe cover.

When the leaves of the book are thus fastened together, and the back A properly glued, the leaves are much more secure, and less likely to get loose, than Vwhen they are fastened in the ordinary manner. A

leaf cannot be removed without tearing it.

This method does not increase the expense of ordinary book-binding, while the book is greatly im- .proved as to its durability and usefulness.

Haring thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is

In combination` with a book, the slits B B, made in the back for receiving the fastening-twine, or thread,

purposes herein shown and described. y

The above specification of my invention ,signed by A and securing the tapes E, substantially as and for the me, this 4th, day of March, 1869.
